MACHINE'FOR MAKING sHnEDDED-Wrm-AT Bisourrs.

Application led .Tune 30, 1905, Serial No. 267,787.

To all whomy it may'concern:

Be it known that I, WILLIAM ERAs'rUs and ,State of Illinois, have invented a new and useful Improvement in Machines for Making Shredded-VVheat Biscuits, of which the following is a. specication.

The object of my invention is to provide a desirable machine for making shredded wheat or other biscuits, and the invention consists in the devicessetforth in the claims. Reference will be had to the accompanying drawing in which- Figure 1 is a plan view of the machine. Fig. 2 is a side elevation of the machine. Fig. 3 is a plan detail of the delivery end of the machine. Fig. 4 is a side sectional detail of the front end of the machine. Fig. 5 is a detail of parts of the timing device. Figs. 6 and 7 are details of the cup spindles. Fig. 8 is a sectional elevation on line 8--8 of Fig. 1. Fig. 9 is a vertical sectional detail through the shredding rolls. ,Fig 10 is a transverse sectional detail showing the guides for the carrier belts. Figs. 11 and 12 are views of the baking cups.

I provide a shredding device of any suitable construction which I show in the drawing as made of rolls 1 and 2 mounted upon any suitable frame 3. The shreds are delivered upon shred carriers of any suitable construction, but I prefer to use the 'belts 4 v which deliver the shreds into baking cups or forms 5 which are carried upon spindles 6 mounted-to revolve in a carrier wheel 7 having a vertical axis 58 in the frame. An air suction-is produced by any suitable means of exhaust (not shown) and is connected by a pipe 8 to a chamber 9 which is connected by cavities 1() and 63 through the spindles 6 to the inside of cups 5 to suck the shreds down into the cups when the cups are in position to be filled. The chamber 9 extends only under the cups that are being filled and the lower side of the wheel 7 fits as a cover over the top of chamber 9. In,V addition to the suction to place the shreds' into the cups, I provide sets of tampers or packers 11 which reciprocate vertically, pushing the shreds into place in the cups as the shreds are delivered by the belts 4. The spindles 6 are made to revolve intermittently by a belt 12 while they are being lled. The carrier wheel 7 is made to move intermittently allowing a period of rest suicient to ll the Specification of Letters Patent.

cups. Thus the wheat or the suitable prepared stock from which the shreds are to be made is placed in the hopper 13 and the rolls convert it into shreds which are formed into shape in the cups 5 which are removed by means and fresh cups supplied in a similar manner.

T he machine is driven by a belt wheel 14 driving a shaft 15 carrying a pinion 16 which drives a span gear 17 on the shaft of one of the rolls and the rolls are geared together by gears 1S. The pulleys 62 on shaft 15 drive the belts 4 much faster than the lineal rate of delivery of the shreds whereby the shreds. assume a straighter position on the belts and are discharged with impact into the forms.

The mechanism for moving the carrier wheel 7 the packers and the cup spindles 6 is driven by the gear 20 on shaft 21 on which there is a crank 22 which is connected by a link 23 to a walking beam 24, having an axis 25 on the frame of the machine. Talking beam 24 is provided with an arm 26 having apertures which carry the packers, the lower ends of which are guided by ,perforated blocks 27, which are supported by the curved hoppers or guide way 28, which directs the shreds into the cups as the shreds are delivered by belts 4. A'shaft 29 and the fixtures thereon act as a timing device and it extends across the machine and is driven intermittently by ratchet 30 and pawl. 31 carried by an arm 32 moved by a link 33 connected to walkin-g beam 24. The shaft 29 carries a block 34-which when in an upward position engages a block 35 on an arm 36 pivoted at one end 37 to the frame of the machineand at the other end 38 connected to a link 39 connected to a bar 40 which is connected to crank 22, The bar 40 reciprocates horizontally with everystroke of the crank. And

(its outer end 41 rides freely upon roller 42 at all times save only when block 34 engages block 35 which engagement lifts the vend 41 of bar 40 and causes the block 43 on bar 40 at' its next stroke to engage one of the pinsv 44 on wheel 7 and move the wheel or carrier two spaces or two cups bringing two' empty cups under the discharge of the belts and removing the two lled ones. Thus the timing of lling the cups is determined by the rate of revolution of the shaft 29 carrying its block 34, this may be varied by causing the pawi 31 to engage more or less teeth ofthe ratchet at a stroke which is accomplished loo , by gravity thereby adjusting themselves to the mass of shreds as they accumulate.

-thrust to the pokers.

52 and dis shreds at each movement of the carrier with by moving the connection df the arm 33. into different holes in walking beam -24 giving more or less stroke to.,pawl arm 32. The shaft 29 carries a belt wheel 45 which drives belt 12' which is trained around suitable guide 'rollers 46, 47, and 48 bringing the belt 12 into engagement with the head block of cup spindles 6 thereby `causing them and the cups'l mounted thereon tov move at each intermltten't movement of ratchet or timing shaft 29, which movement takes place while the. acking pokers are above the cups 5, there y not disturbing the shreds in the cups by the revolution of the cups. The lpokers 11 slide loosely inlV their supports and go down Weights 49 are provided to give, proper Above the -cup spindles on the carrier wheel 7.l there is a cutting disk 50 provided with apertures 51 over the cu spindles. ounted to`slide on the tbp of cutting disk 50 there is fixed plate 52 to which the ers 28 are attached. The late curved ho 5() act as a shear to cut o the the cups. The cups 5 are perforated at the bottom to provide a connection to' the suc-- tion chamber 9 through the cavities 10 and l 63 of. spindles 6. Whereby the suction can Vacton the shredsas they fall into the. cups.

Instead of suction I, may use an air blast from above but I prefer to use the suction.

Below the rolls 1 and 2 lthere are provided guide or delecting plates 53 and 54 fondirecting thefalling shreds upon the center of' carrier belts 4.- The belts 4 are made of two thicknesses, one on top of the other and the upper or outer one is the thinner and more flexible of the two and they are connected together `by rivets 55 along a central line. Albng the .upper or carryin side of the belts there are provided guide cards 56, which extend inward between the parts of the belt causing the upper layer to assume the shape 4 of a trough thereby holding the shreds in place on the belt and preventing thus dis'- placementas they are carried along. v

The`rolls are provided with suitable adjustments to hold them' in position to' each other and also with suitable Scrapers 57 tostrip the shreds ofl" them. -The cups 5 are the subject of anotherpatent and they'are made in two pieces, the outer or shell piece sits over the top of the spindle 6 on to the shoulder 59, while the conc piece rests on the surface 60. Thus the cups are held upon the spindles, yet may easily be removed as ther'e is clearance between the top of the cupsand the under side of plate50.

In place of .theyrolls for producing the shreds I may use any suitable shredding device or provide a suitable source of supply of the shreds in any manner. l
